I agree. In the center is the best place. Shortest route, and most protected.

So, the group consensus is metal down the middle. Whats the existing lines made of? I thought it was metal...
I plan on blowing them out, and clean w/ fuel stabalizer (IMG:style_emoticons/default/confused24.gif) sound good? |

Stock fuel lines were hard plastic.

I wouldn't replace them unless they need it. I'd just flush them like you are planning. They are made of some kind of hard plastic.

I'd have to disagree with Anthony...
These plastic lines are how old? 25, 30 years? They are known to become brittle (which is bad news) Replace 'em with steel ones (unless you already have steel replacements) now, while everything is outta the car (easier access) Just my 0.02 euro's cheers, Jeroen |

There was a post with this topic a few weeks back that went on and on about fuel line replacement. Do a search and check it out. It has all the options and pros and cons.

It has all the options and pros and cons. I was following that thread... Do the stock lines have any steel tubing, like where it exits tunnel under the tank? I have steel connections there. The existing plastic at the rear is brittle, broke already. Does this crap run all the way thru the tunnel and connect to the tubing/nipples I'm talking 'bout? |

They are known to become brittle (which is bad news) Jeroen, even Br@d said in the other topic that he looks for good used lines. I assume he's talking about good used 30 year old lines. Sure, lines should be replaced if there is a problem with them but I don't think they need replacing just because they are old. |

I say replace them, the job isn't that bad (even I was able to do it) I used copper tubing but you could use steel, or even braided stainless if you can find the right size, then get good new neoprene fuel line for the terminal connections ( it likes the new gas) and a few mo3 size clamps and you're in business.

The existing plastic at the rear is brittle, broke already. Does this crap run all the way thru the tunnel and connect to the tubing/nipples I'm talking 'bout? The stock lines are steel up front, where they go through the grommet. The plastic is (more or less) just pushed onto the steel bits, and then runs back through the tunnel and exits into the engine bay. There is practically never a problem with the lines in the tunnel, unless they get physically damaged by some intrusion. (Screw, drill bit, etc.) In the engine bay is another story. They get exposed to heat and chemicals and such, and can eventually get brittle and break. As long as you can safely get rubber lines onto them, I don't think there's a lot of problem just keeping them. I'd use SS truck hard brake line. Aluminum and copper have too many potential issues. Copper in particular... --DD |

"Best"? I suppose that would be "where the tubing is still pliable". It would be nice if you kept the stock runs of tubing vs. hose, but I don't see that it's very necessary. Just make sure you have things routed so you don't start wearing through your hoses (BTDT, got the underwear!) which is no fun.
